Application Jane 27, 1935, Serial No. 28,639 9 Claims. (Cl. 4-291) This invention relates to removable sink strainers or perforated containers for drain openings.

Sink strainers have been in use but in such strainers it is necessary to fit the strainer in the drain opening by alining slots and lugs or'projections. In other words, the user has to be careful to replace the strainer in a predetermined position or else it will not operate. In these prior strainers one position usually is a correct position. I have invented a new sink strainer or perforated oontainerwhich is operative in any position. and which does not need to be correctly positioned in the drain opening. It is only necessary to place the strainer or perforated container within the drain pipe and move a handle or bail on the strainer or container to one position or the other to place the strainer in open or closed position. The bottom of the strainer is closed and has a valve which cooperates with a valve seat positioned in the drain pipe, so that when the strainer is in lowered position the valve is closed and when the strainer is in raised position the valve is open and permits the flow of liquid through the drain opening. The strainer is removably mounted within the drain opening so that it may be taken by the handle or ball and removed and crumbs or other solid material may be taken out and thrown away without the possibility of clogging up the drain opening. The

handle or ball which is operatedto raise or lower the strainer or container is also used when the strainer or container is removed from the drain opening. I

The object of my invention is to provide a removable sink strainer or perforated container which is cheap to manufacture and which is very easily operated in any position and which is also provided with means whereby the flow of liquid from the sink or other liquid container may be ssntrolled.

in lowered position so as to close the valve and prevent the outflow of liquid through the drain opening; and

Fig. 4 represents a perspective view of a part 01 the perforated container or strainer.

Referring now to the drawing, the reference character it designates a portion of a sink or thevlike provided with a drain opening H2 in which a device made according to my invention is mounted. The tubular member l4 positioned in 5 opening i2 is provided with a flange l6 which rests on the top of the wall of the container or sink- I0. The tubular member or coupling M has an annular or sleeve portion l8 which fits the drain opening. Beneath the portion i8 the tubu- 10 lar member has an annular shoulder or ledge which extends inwardly. Beneath shoulder or ledge 20, the tubular member is formed with an annular bead 2! which assists in guiding the strainer or perforated container later to be de- 15 scribed. The lower portion of tubular member is is threaded as at 22, this threaded portion has. a slightly smaller diameter than the sleeve portion it. The clamping nut 24 is threaded on the threaded portion 22 and clamps the washer 2 26 against the underside of the wall of the sink or container it to form a water tight joint. Adjacent its lower end the tubular member. is provided with an inwardly directed flange 3m Extending downwardly and inwardly from I the flange 3a is the tapering portion 32 which forms a valve seat. The lower end of the tubular member it is provided with openings 8d formed by straps $5 to form. a supplemental strainer. I

Connected to the lower end of the tubular memher id and forming an extension thereof is a pipe 38 having a flange 33 which is held against washer d9 abutting the underside of the inwardly directed flange W on the tubular member by the coupling or clamping member 32.

Removably mounted within the tubular memher is a. strainer or periorated container M. The strainer dd has an annular flange it which is received within the annular or sleeve portion it of the tubular member to assist in positioning the strainer within the tubular member. The lower end of the strainer or perforated member id is closed as at 68 and is connected to the body of the strainer lit by the tapered annular portion 53 forming a valve on the lower end ofthe strainer it. The valve 56 cooperates with the valve seat 32 on the tubular member so as to close the outlet from the sink or the like when the strainer is in lowered position as shown in Fig. 8.

The strainer or perforated container l i is pro- 50 vided with means adjacent its upper end whereby the strainer or perforated container may be moved to open or close the valve at the bottom I of the tubular member M. This same means serves as a handle when it is desired. to remove 5 thestrainerfromthetubular member ll. This means'comprises a handle 52 which is pivotally mounted adjacent the top of the strainer or perforated container. This handle 52 comprises a curved portion I4 formed with a projection 55 which. facilitates operation of the handle 52.-

The handle also has angular portions 58 which extend through openings 5! in the wall of the perforated container 44 and form the pivotal-mounting. The ends of the handle comprise legs or extensions ill which are adapted to cooperate with the shoulder or ledge "on the tubular member I to move the perforated container into raised position. When the handle '52 is turned or rotated to the position shown in Fig. 2, the ends of the legs or extensions 80 of the handle "are moved against the shoulder or ledge 20 of the tubular member II to act as a lever and to raise the perforated container. position the valve 50 on the perforated container is raised or moved away from the valve seat 32 on the tubular member I and in this position liquid is permitted ,to flow from the sink or other'container. When the handle is moved or rotated to the position shown in Fig. 3-the handle parts become inoperative and'the perforated container or strainer is in lowered position so that the valve It rests on the valve seat 32 and prevents the flow of liquid from the sink or the like. The handle 52 is pivoted substantially centrally of the strainer so that in either position shown in Fig. 2 or Fig. 3 the handle abuts or rests on the top of the container'and so is maintained in an easily accessible position.

The operation of the devicev will be apparent from the above description. When it is desired to keepliquid in the sink or the container, the handle'52 is moved to the position shown in Fig. 3 so that the legs or extensions 60 on the handle do not rest on the ledge or shoulder 20 on the tubular member ll. In this position the valve formed by the lower portions of the strainer and the tubular member is closed. When it is desired to permit the flow of liquid from the sink or container, the handle 52' is moved or rotated to the position shown in Fig. 2 and during such movement the legs or extensions 60 on the handle act as levers on the ledge or shoulder 20 to raise the strainer or perforated container so that the valve It on the strainer is moved away from the valve seat 32 on the tubular member II and liquid ispermitted to flow from the sink or the other container. If the water in the sink or container contains solid particles or other solid material, the strainer retains them and permits the liquid to'flow through the strainer. After the liquid is emptied from the sink or container, the strainer or perforated container I4 is removed by grasping the handle 52 and the contents thereof emptied. After this operation the strainer is returned to the tubular member and is placed in either of the positions shown in Figs. 2 or 3.

From the foregoing it will be apparent that it is not necessary to replace the strainer in any particular position as the strainer may be operated in any position, that is the legs or extensions 60 may always be made to cooperate with the ledge or annular shoulderformed on the tubular member ll .to place the strainer in either raised or lowered position. 7

From the foregoing it will be apparent that I have disclosed a relatively simple strainer or cup container which-is cheap to manufacture and which is easily operated in any position.
